What does a commercial boiler service involve?

A commercial boiler service covers combustion analysis, heat exchanger inspection, safety device testing and flue gas checks — legally required for all commercial properties.

What Does a Commercial Boiler Service Involve?

Commercial boiler servicing is more comprehensive than a domestic service and is a legal requirement under the Gas Safety (Installation and Use) Regulations 1998.

What's Included in a Commercial Boiler Service

  • Combustion analysis — flue gas sampling to verify efficient and safe combustion
  • Heat exchanger inspection — checking for cracks, fouling or scaling
  • Burner inspection and cleaning — removing carbon deposits
  • Safety device testing — pressure relief valves, thermostats, gas valves
  • Flue and ventilation check — ensuring safe exhaust
  • Controls and BMS verification — if applicable
  • Full written report — including Gas Safety Certificate

Frequency

Commercial boilers should be serviced annually as a minimum, with some larger plant rooms requiring 6-monthly inspection.
